  Q: How to replace the A/C Condenser in a system on Buick Rainier?

  A: Frigenrnt recovery begins before installing a new condenser. The compressor discharge hose connection requires removal at both ends from the condenser by untightening the nut and hose. After removing the evaporator tube nut installed on the condenser extract the evaporator tube from the condenser . The replacement process starts with Hood Latch removal and condenser retaining screws before removing the condenser from its radiator placement. When replacing the condenser install it back onto the radiator while adding new refrigerant oil. Fasten the condenser into position with the retaining screws until they are torqued to 5 n.m (44 lb in). Put the Hood Latch back into place while linking the evaporator tube to the condenser . Install the retaining nut to the evaporator tube at the condenser before tightening it to 28 n.m (21 lb ft). Connect the compressor discharge hose to the condenser while installing its retaining nut before tightening both to 28 n.m (21 lb ft). Complete system evacuation and recharging follows a leak examination of fittings through utilization of the halogen leak detector (J 39400-A).
